This question already has an answer here:
I'm trying to remember a book title, wherein the main character pretends to be in a coma, and is a telepath. He travels the 'net with his mind and at one point, comes across a number of minds that are in orbit on a satellite. They greet him, and this startles him so much that his life signs in the long term care facility where he's "parked" potentially(?) raise the alarm that he's conscious. (The book goes into some detail about how much control he has to leverage over his physical body to pull off the guise of a coma.)
The only other part of the book I can remember is a relatively graphic scene where a female character--I believe one of a team in pursuit of the main character--is descending in an elevator with a man, perhaps into the facility where the main character's "comatose" body is located. For some reason I can't remember, she feels compelled to suddenly give the man oral sex and suddenly bite off his penis.
